摘　　要：本文总结了鞍钢高炉喷吹烟煤工业试验的经验和成果。采用以控制含氧浓度和火源为重点的技术,形成了一套完整的喷吹烟煤工艺体系。该系统能满足喷吹高挥发分烟煤的要求,试验期间炉况稳定顺行,各项技术经济指标得到改善。鞍钢5座高炉100％喷吹烟煤,喷吹量增加30％,生铁增加3.6％,焦比降低25kg/t,煤焦置换比提高0.1～0.2,吨铁成本降低4.12元。This paper Summarizes experiences and achievements in the industrial experiment of bituminous coal injection into BF at Anshan Iron and Steel Co. Important technique consists in controls of oxygen concentration and fire-source. An integrated technology system with bituminous coal injection has been formed. This system has completely satisfied the requirements of high.volatility bituminous coal injection. During the experiment, furnace operated smoothly, all technical and economic indexes have been improved. At Anshan Iron and Steel Co., five BFs operate 100% bituminous coal injection, injection rare increases by 30%, output of hot metal increase by 3.6%, coke ratio decreases by 25 kg/t, replacing ratio of coke by coal increases by 0.1～0.2, and cost decreases by 4.12 yuan per ton hot metal.
